Central midfielder Wanyama is the only signing to force his way into the starting XI on a regular basis and has looked impressive alongside Mousa Dembele.

Mauricio Pochettino’s side have won just once in their last nine games across all competitions and are struggling to find consistency.

Ex-Spurs midfielder Jenas claims that the north London club are now struggling as a result of their summer signings.

“I think they could have gone harder in pushing people like Eriksen with better players in that area,” Jenas told BBC Radio 5 Live. “They could have got a better option than Janssen in that attacking area.

“I think they half played it safe and relied a lot on their youth and people like Sissoko, who I don’t think suits Spurs atoll. I think they’re paying for it now. I think they can’t wait for January.”

Janssen, 22, is one player that has come under criticism this season for his contribution and he is still without a goal from open play.

The striker has scored three penalties in his opening 19 appearances for Spurs and does not look like pushing Harry Kane for a starting position.

France international Sissoko, who completed a £30million move to White Hart Lane on deadline-day, has endured a torrid start at his new club.

The 27-year-old is without a goal or an assist in his 10 appearances and has failed to put pressure on wingers Christian Eriksen or Erik Lamela.

Spurs are only four points behind Premier League leaders Chelsea despite the recent dip in form, who they face at Stamford Bridge on Saturday.

Pochettino’s side suffered a disappointing exit from the Champions League mid-week and will be looking to get back on track against London rivals Chelsea.
